    SubjectRe: 2.6.29 regression? Bonding tied to IPV6 in 29-rc5
    We have the same issue with the qeth_l3 driver (it requires IPv6 symbols).
    Distributors compile with IPv6 but some customes want to disable IPv6 without
    building a custom kernel. If there would be a generic solution to address
    this kind of runtime IPv6 dependencies this would be creat. schrieb:
